DUMP-CAR.

Specification of Letters Patent.

Patented Dec. 7, 1920.

Application filed July 26, 1919. SeriaI No. 313,572.

To all whom it may concern-1 Be it known that I, JAooB OoHsNEn, a citizen of Switzerland, residing at Zurich, in the Canton of Zurich, Switzerland, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to an improved dumping car and more particularly to a type wherein one or more carriage supports move transversely of the car and carry a bucket, which is mechanically tilted to discharge its contents. 7

The object of this invention is the pro-' vision of a device of the character hereinafter set forth, which is capable of discharging quantities of material at a considerable distance from the car proper and by reason of the compact construction, several such units may be independently mounted upon the platform of a single car.

A further object of the invention is to pro-' 'vide an efficiently operated bucket, which by reason of its design is capable of quickly discharging any material within a'comparatively short time.

The invention consists in the structural features and combinations of parts hereinafter fully described with reference to the accompanying drawings wherein,

- Figure 1, is a side elevational View of a car showing two dumping buckets and their supporting parts arranged therein.

7 Fig. 2, is a vertical sectional view on the lines A--B of Fig; 1, showing the bucket in the tilted or tipped position.

Fig. 3, is a front elevational view'of one of the buckets mounted in its supports and held in normal position.

Referring to the drawings a indicates a bucket having a cylindrically shaped bottom and outwardly flared sides, the ends however being straight and provided with projecting pivot pins Z). The bucket or is adapted to operate in a transverse direction to the axis of the car upon which it is mounted, in'

other Words the pivotal axis of said bucket a is parallel to the axis of the car. A supporting carriage frame (Z is provided with centrally located bearing blocks 0 at opposite sides thereof and raised upon suitable strengthening bars slightly above the plane of said supporting frame (Z. The bearing blocks 0 have vertically extending slots to accommodate the pivot pins 6 of the bucket 0;, and it will be noted with reference to the drawings, that the bucket may readily be removed by raising same out of the slotted openings in the bearing block. This construction is particularly desirable when the buckets are loaded elsewhere than on the car, and transported by derrick or other suitable means, and suspended above the bearing blocks until the pivot pins I) register with the slotted openings and permitted to drop therein. I a

The supporting carriage frame d substantially surrounds the bucket a and comprises a rectangularly arranged frame having parallel longitudinal channels beams 9 connected at their ends by bars upon which a series of rollers e are mounted. The lower extension of the carriage frame d is made up of parallel channel beams arranged at each end of the frame on a plane parallel with the bottom of the bucket a. The construction described above provides a substantially rigid supporting carriage frame capable of withstanding any strain to which. the latter may be subjected.

. The supporting carriage frame d is adapted to be guided in its lateral movement and likewise supported by a superstructure g mounted transversely of the car upon longitudinally extending I beams k. The I beams It extend the entire length of the car and as shown in'Fig. 1, may support one or more complete dumping devices. The guide frames g'are' arranged at opposite sides of the supporting frame cl and are provided with transversely extending channel beams f. A box beam f is secured to the I beams h and is parallel to the upper channel beams f havin their ends connected by the up-. rights of g. A series of rollers 2' is mounted in each of the box beams f and protrude through slots in the upper face of the beam. The under surface of the channel beam f and the upper surface of the lower channel beam of the supporting framed areprovided with groove guides f and d repectively, said grooves-being adapted to accommodate the rollers e and It will be noted that the rollers e are mounted in the movable supporting carriage frame, while the rollers i are mounted 1n a portion of the stationary frame 9, and in accordance with this construction, when the frame d is extended as shown in Fig. 2, the strain of the entire load will come under the channel beam By reason of its rigid connection with the I beams h and platform of the car proper, the strain is evenly distributed throughout the structure;

Mounted between the stationary box beams f and journaled therein are winding drums 0 adapted to receive the conveying and tilting chains p and 79 The bearing shafts of the drums 0 protrude outside of the frame 9 and have mounted thereon sprocket wheels Z Endless sprocket chains]: connect the sprockets Z with small sprocket wheels Z mounted upon and adapted to turn with a crank shaft m the outer end of which is' formed as a crank handle. The shaft on is mounted in bearings supported in the channel beam 7 and is provided .with a ratchet disk the teeth of which are adapted to be engaged by pivoted dogs also mounted upon the beam f.

Each of the parallel channel beams g is providedwith a hook 1" depending from the under face of-the beam midway of its length I thereof, and said hooks are designed to receive the end links of the chains 17 and p as described hereinafter. Similar hooks s are secured to the outer edge of the rim of the bucket a, each hook being midway of the side of the-bucket and adapted to receive the end link of one of the chains p and p in accordance with the operation of the device as set forth hereinafter.

The supportingI beams h extend the entire length 'of'the car and each of-the outermost members supportsthe edge of a distributing'board t. Theboar'dt is inclined from the: top of the I beams h to the edge of-the car platform, and also extends inwardly from said I beams to a still higher point located midway of the car platform beneath the bucket. A central opening in the inner: portion of the board t is provided to accommodate the winding drums '0, which is clearly shown in Fig. 2, of the drawings.

In the operation of each of the dumping buckets andtheir traveling supporting carriage frames, the following description will fully disclose the-functions of one unit'and it will be understood that, any number mounted upon the same car platform will be controlledandoperated in the same manner.-

When it-is desired to dump the material from the-bucketcatothe left of the car as shown inFig 2, the ehains p and will be unwound fromtheirrespective drums 0. The end link of the chain p carried by the left hand'dr-umwill be hooked over the'hook r on-.-the right-hand-beam g of the movable supporting, carriage frame d, likewise the end link=of-the chain p -Icarriedby the right hand-drumwill be& hooked over the hook I s depending:from theleft hand-.side-of the bucket a'.- This will place the carriage supto be moved toward the left side of the car and tipped.

The left hand drum is operated by the sproeket'chain la'and handle m, which is rotated counter clockwise. The winding up of the chain 19 about the left hand drum 0 will draw the carriage frame d toward the left of the car. The chain 29 extended by the righthand drum 0 may at this point he wound up about the latter, which will rock the bucket a on its pivots Z). The rotation of the sprocket chain 71: and sprockets Z and Z are controlled by the crank handle m, which in the present'instance will be moved clockwise.

The material having thus been dumped onto the inclined side of the car will continue its outward travel to the edge of the latter where it will fall to the ground or to a conveyer if one be provided. The return of the bucket to its upright position will be automatic, after release of the chain 72 due to the fact that the'pivots Z) are considerably above its center of gravity. The chain 9 being u'nhooked and theend linkof the chain 11 carried bythe right hand drum is hooked over the hook 1" depending from the right hand channel beam The crank handle m is again rotated toward the-right winding the chain 19 and drawing the carriage frame 9 toward the right until itsnormal position is reached.

It will be understood that by reversing the operations noted above the carriage 9 may be made to move to the right and the bucket a may be made to dump at the right hand side of the 'car.

Having described the nature of the invention and its operation, what I claim is,

1. A. dumping car, having a superstructure mounted thereon, a carriage frame slidably mounted in said superstructure, antifriction members carried by the superstructure and carriage frame and adapted to sustain said carriage frame, a hollow container mounted in said carriageframe and having a cylindrical bottom portion terminating in upwardly extending flared sides and end portions having pivots mounted. thereon, said pivots being rotatably supported in said carriage frame, and windlasses mounted in a portion of said superstructure and having chains'adapted to be wound about said windlasses the free ends'of said chains being detachably connected respectively to a portion of the container and carriage, whereby the latter may be moved and the container tilted to discharge its contents.
